Lập Trình C

Bài tập - Quản lý hình chữ nhật - struct trong C - Lập trình C BT1929

1. Tạo 1 struct gồm các thuộc tính sau -> float : dientich, float chieudai, float chieurong

2. Tạo mảng list gồm 5 HCN

3. Nhập thông tin chiều dài và chiều rộng cho 5 HCN trên

4. Tính diện tích của từng HCN và lưu vào biến dientich tương ứng

5. Tính tổng diện tích 5 HCN trên

Liên kết rút gọn:
